baxi combi 105e ch fine no dhw

[silverknight]

Hi Guys,

I have a problem with my baxi combi 105e.

CH works fine but DHW does not recognise the hot tap being turned on. This happens in both CH/DHW and DHW only settings. Water may get up to luke warm and then run as cold as the mains cold.

DHW will heat the reserve tank to any temp set and I can get hot water by switching to DHW only and running the tap as system tries to heat the reserve tank.

Any ideas?

You have a 105 instant. HW Diaphragm has gone and needs replacing

Thanks for the quick reply.

Is there any way of checking the diaphragm before I spend any money?

Cheers,

It costs no more than a tenner

Thanks very much all fixed. Diaphragm had a hole in it.
